Fig. 4 shows the wireless communication system with multiple wireless devices 400 that wherein can utilize the embodiments of the invention that disclose herein.The wireless communication system 400 of Fig. 4 can be an example of the wireless communication system 100 of describing in conjunction with Fig. 1 above.For instance, the base station 402 of Fig. 4 and radio communication device 404 can correspond respectively to base station 102 and the radio communication device 104 of Fig. 1.
For example, communication in wireless communication system 400 (, multi-address system) can realize via the transmitting on one or more wireless links such as down link 480 or up link 482 such as.Can export (SISO) via single input and list, input and single output (MISO) or input and communication link described in many output (MIMO) system mades more more.Mimo system comprises and is equipped with respectively multiple (N t) transmitting antenna and multiple (N r) reception antenna is for reflector and the receiver of data transmission.SISO and MISO system are the particular instances of mimo system.If utilize the extra dimension being produced by multiple transmitting antennas and reception antenna, mimo system can provide improved performance (for example, higher position reason amount, larger capacity or improved reliability) so.
Mimo system can be supported time division duplex (TDD) and Frequency Division Duplexing (FDD) (FDD) system.In TDD system, down link 480 and up link 482 are transmitted on same frequency zones principle of reciprocity are allowed according to uplink channel estimation downlink channel.This makes to launch wireless device can extract transmit beam-forming gain from the communication that transmitting wireless device receives.
Wireless communication system 400 can be the multi-address system of communicating by letter that can for example, support by sharing free system resources (, bandwidth and transmitting power) with multiple radio communication devices 404.The example of this type of multi-address system comprises code division multiple access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) (W-CDMA) system, time division multiple access (TDMA) system, frequency division multiple access (FDMA) system, OFDM (OFDMA) system, single-carrier frequency division multiple access (SC-FDMA) system, third generation partner program (3GPP) Long Term Evolution (LTE) system and space division multiple access (SDMA) system.
Radio communication device 404 can be communicated by letter with zero, one or more base station 402 at any given time in down link 480 and/or up link 482.As mentioned above, down link 480 (or forward link) refers to the communication link from base station 402 to radio communication device 404, and up link 482 (or reverse link) refers to the communication link from radio communication device 404 to base station 402.
Radio communication device 404 can operate in some patterns such as such as active mode, standby mode and passive mode or state.In active mode, radio communication device can have seedbed and one or more base stations 402 swap datas (for example, voice or data).In standby mode (, idle mode), radio communication device 404 can monitor that paging channel is to obtain message, for example general beep-page message (GPM) or be addressed to the direct message of radio communication device 404.In passive or park mode, radio communication device 404 is by reducing power consumption by down circuitry as much as possible.In other words,, in passive or park mode, radio communication device 404 does not monitor paging channel or carries out joining procedure.
The power consumption of radio communication device 404 in standby mode reduced available battery resource.This shortens the time between battery recharge conventionally.Power consumption in standby mode is conventionally than the large manyfold of the power consumption in passive mode.Any minimizing of the time quantum spending in standby mode can cause directly and significantly the improving of overall cell life-span of radio communication device 404.Therefore, need to make the power consumption of radio communication device 404 in standby mode minimize to increase battery life.Power efficiency and also save and be more rich in feature and become further important along with radio communication device becomes.
In a configuration, for reducing the power consumption in standby mode, can at the appointed time the message in paging channel be sent to radio communication device 404.For instance, in CDMA2000 system, paging channel is divided into " time slot " (, slotted paging channel) of numbering.Each time slot can be relevant to time slot cycle index (SCI).
Base station 402 can assign one or more time slots with paging receiving message to radio communication device 404.For instance, under IS-2000 standard, paging channel is split into two Paging Channel Slots, and each has 80 milliseconds of (msec) duration.Each Paging Channel Slot is further split into four 20msec frames or sub-slots.The radio communication device 404 of one group can be assigned to each Paging Channel Slot.
In slotted paging channel, radio communication device 404 periodically and discontinuous supervision paging channel to obtain from the message of base station 402.In other words, radio communication device 404 can wake up with decoding paging messages at particular time-slot (corresponding to the time slot cycle index (SCI) that is assigned to radio communication device).Before the time slot that radio communication device 404 is assigned at it or sub-slots, wake up from passive mode, be switched in standby mode to detect beep-page message, and enter active mode and obtain message to process paging channel.In other words, radio communication device 404 can for example, wake to process the beep-page message via reception of wireless signals up at predetermined sub-slots number place (, just before it).Radio communication device 404 can be got back to passive mode in the situation that not needing additional communication.In this way, save power by shortening the standby mode time.
In this configuration, if the message receiving needs radio communication device 404 to carry out additional act, radio communication device 404 will remain in active or passive states so.When not wait for or active state in time, radio communication device 404 turns back to passive mode.But this configuration may have problem, because if base station 402 sends to radio communication device 404 by beep-page message in passive or park mode time, beep-page message will be can't help radio communication device 404 and be detected so.
In addition, under this configuration, if base station 402 changes the time slot or the sub-slots that send beep-page message, the sustainable beep-page message missing from base station 402 of radio communication device 404 so.Or if base station 402 sends beep-page message being different from Current Delegations in the time slot of radio communication device 404, radio communication device 404 can be awake until beep-page message detected so.In other words, radio communication device 404 by unnecessary for wherein to send the time slot of beep-page message awake and will be without waste power.
In another configuration of paging channel of dividing time slot, radio communication device 404 keeps awake to detect the beep-page message from base station 402 for two 80msec time slots, or until receives beep-page message.Described two time slots can be divided into four 20msec sub-slots separately.In this configuration, radio communication device 404 can for example, keep awake for eight 20msec (, 160msec).
In optimum network, base station 402 sends beep-page message to radio communication device 404 all the time during the first sub-slots.This enters park mode in short time by permission radio communication device 404 after receiving beep-page message.In this way, the time spending in passive mode increases, because radio communication device 404 will not continue search beep-page message in standby mode.
In non-optimum network, base station 402 can send beep-page message to radio communication device 404 during sub-slots after a while.Base station 402 can send beep-page message and receive described beep-page message to guarantee all radio communication devices 404 during sub-slots after a while.But the method may poor efficiency, because causing radio communication device 404 to remain in standby mode, it continues than the cycle of the essential length of institute.Therefore,, in the time that base station 402 is later than the first sub-slots and sends beep-page message to radio communication device 404, radio communication device 404 continues in standby mode not receive by remaining on or the extra sub-slots of decoded information.For instance, if base station 402 sends beep-page message to radio communication device 404 in the 8th sub-slots, radio communication device 404 can unnecessarily remain on lasting the first seven sub-slots (, 140msec) in standby mode so.
In another configuration, radio communication device 404 can adopt quick paging channel (QPCH).QPCH is the channel separating with paging channel.QPCH is paging receiving message not, but for detection of informing whether radio communication device 404 is switched to the position of standby mode with paging receiving message on paging channel from passive mode.
QPCH is combined with and serves as the control channel of paging channel with paging channel.Each QPCH time slot is associated with corresponding Paging Channel Slot, but launches before the Paging Channel Slot that is associated.For instance, the time slot 2 of QPCH time slot was launched 100 milliseconds (msec) before the time slot 2 of paging channel.Paging Indicator position warning radio communication device 404 on QPCH is launched in decoding beep-page message is about to be associated Paging Channel Slot in paging channel.But QPCH can fail to receive or decoding paging indicating bit.In the case, the beep-page message that sends to paging channel also can not be received the decode by radio communication device 404.
QPCH also can send to false alarm radio communication device 404.The in the situation that of false alarm, QPCH inform radio communication device 404 will be in next time slot in the time not there is not beep-page message paging receiving message.This causes radio communication device 404 owing to operating and wasting power in standby mode when not in paging receiving message.
As prior statement, base station 402 can send to beep-page message radio communication device 404.Beep-page message can be direct paging message 486 or general beep-page message.In some instances, general beep-page message (GPM) can be empty general beep-page message 488.In addition or as an alternative, direct paging message 486 also can be general beep-page message.
Base station 402 can comprise beep-page message module 484, and it produces direct paging message 486 and/or empty general beep-page message 488 and sends it to radio communication device 404.Radio communication device 404 also can detect direct paging message 486 and/or empty general beep-page message 488.Radio communication device 404 also can detect the data of unwanted next message of page match algorithm.
Direct paging message 486 can be warned the existence of radio communication device 404 incoming call system update parameters (for example, Overhead Message).If radio communication device 404 detects direct paging message 486, radio communication device 404 can be carried out joining procedure so.
Empty general beep-page message (GPM) 488 can indicate all direct paging message 486 to be sent by base station 402.If radio communication device 404 detects empty general beep-page message 488, radio communication device 404 can enter immediately dormancy (for example, passive mode) rather than wait for more beep-page messages so.
Can utilize therein in a configuration of the embodiments of the invention that disclose herein, radio communication device 404 can comprise optimizes wake module 460.Optimize wake module 460 and can help to increase dormancy time.Optimizing wake module 460 can allow radio communication device 404 wakeup time of radio communication device 404 to be adjusted to the sub-slots that is later than the first sub-slots.In this way, radio communication device 404 can enter standby mode in sub-slots identical when with positive paging receiving message.Therefore, the unnecessarily minimizing of the time quantum in standby mode of radio communication device 404.
In addition, optimization wake module 460 can reduce the stand-by period of a reservation in slotted mode.In this way, optimize wake module 460 and can reduce that two SIM are two treats two conflicts of subscribing between waking up in (DSDS) device (or any device that contains multiple SIM).
Optimization wake module 460 can comprise one or more and wake record 462 up.Each wakes record 462 up can be corresponding to stored sub-slots number 464, counting 466, community ID468, PN (pseudo noise) code 470 and/or Record ID 472.The number that wakes record 462 in optimization wake module 460 up can be depending on the number of radio communication device 404Ke Yong community ID468 and PN code 470.
Once only one wake up record 462 can be active.Active wake record up 462 can be corresponding to the current area ID468 of radio communication device 404 and current PN code 470.Table 1 illustrates that two are waken up record 462.

Table 1
The sub-slots number 464 of storing can refer to sub-slots or the frame of nearest decoding paging messages.In other words the sub-slots number 464 of, storing can refer to need radio communication device 404 in standby mode with detect and decoding paging messages for specific sub-slots.Base station 402 can be assigned and be assigned and wherein will receive the decode the required sub-slots of beep-page message again.Assign based on the sub-slots of base station 402, radio communication device 404 can change and/or upgrade the sub-slots number 464 of storing.In other words, new sub-slots number substitutes the sub-slots number 464 of storing.
In some instances, wake record 462 up and can only there is a sub-slots number 464 of storing.This can stored sub-slots number 464 for wake up record 462 current forward countings for sub-slots number time occur.In other words, base station 402 is just sending beep-page message during the sub-slots number identical with stored sub-slots number 464.For instance, base station 402 sends beep-page message in the time that stored sub-slots number 464 is sub-slots 6 during sub-slots 6.
When radio communication device 404 is in sub-slots when decoding paging messages, preserve and/or increase progressively counting 466.If radio communication device 404 is decoding paging messages in the sub-slots with the sub-slots number identical with stored sub-slots number 464, can increase progressively so counting.If radio communication device 404 is decoding paging messages in the sub-slots with the sub-slots number different from stored sub-slots number 464, the sub-slots number 464 stored so can be set as new sub-slots number and counting 466 can reset (, being set as 0).
For instance, if empty general beep-page message (GPM) 488 or direct paging message 486 in the 3rd sub-slots, detect, the sub-slots number stored so can be set as 3 and counting 466 can be set as 0.If radio communication device 404 (subsequently, corresponding to being assigned in next time slot of time slot cycle index (SCI) of radio communication device 404) in the 3rd sub-slots, decode another empty general beep-page message 488 or direct paging message 486, the sub-slots number stored so can remain 3 and counting can be incremented to 1.This process can repeat as shown in Table 2 below.For instance, radio communication device can receive two extra beep-page messages, as shown in Record ID in table 2 4722 and 3.

Table 2
If radio communication device 404 is decoding paging messages in the 4th sub-slots subsequently, the sub-slots number 464 stored so can be set as 4 and counting 466 can be reset to 0, as shown in Record ID in table 2 4724.For example, although it should be noted that for sub-slots 3 and replace multiple records (, Record ID 4720-3), can adopt the single record 462 that wakes up for sub-slots 3, wherein only count 466 each extra beep-page message receiving for sub-slots 3 places and change.Under a method after this, the Record ID 4720 in table 2 will be relevant to sub-slots 3, and Record ID 4721 will be relevant to sub-slots 4.
In some configurations, when radio communication device 404 had previously been counted but current not in the sub-slots of counting when decoding paging messages at it subsequently, counting 466 can reset to 0 or counting 466 can continue to increase progressively.For instance, in table 2, if radio communication device 404 decoding paging messages in the 3rd sub-slots subsequently, Record ID 4725 (not shown) can be reset to 0 and maybe can be incremented to 4 so.
Radio communication device 404 also can comprise continuous sub-slots threshold value 474.Sub-slots threshold value 474 can be the threshold value defining in advance continuously.In a configuration, sub-slots threshold value 474 can be configurable (for example, capable of regulating or variable) continuously.For instance, if sub-slots threshold value 474 is configurable continuously, base station 102 can change or upgrade continuous sub-slots threshold value 474 on radio communication device 404 so.
In the time that counting is equal to or greater than continuous sub-slots threshold value 474, optimization wake module 460 can receive beep-page message sub-slots 476 and be set as stored sub-slots number 464.Beep-page message receives sub-slots 476 and can indicate radio communication device 404 should in which sub-slots, start paging receiving message to radio communication device 404.Originally, beep-page message receives sub-slots 476 and can be set as the first sub-slots (for example, boundary of time slot).For example, in the time that counting 466 resets (, being set as 0), beep-page message receives sub-slots 476 also can reset to the first sub-slots.For instance, if beep-page message receives sub-slots 476 and is set as the 3rd sub-slots, radio communication device 404 can keep dormancy during the first sub-slots and the second sub-slots so, but before the 3rd sub-slots, wakes up with paging receiving message and carry out page match.
Use to optimize to wake up and can increase the park mode of radio communication device 404 time.According to the sub-slots of launching therein beep-page message, the difference that can realize the park mode duration increases.Following table 3 is shown the percentage that the sub-slots number park mode time based on launching therein beep-page message increases.
Table 3
Table 3 shows that optimizing wake module 460 can reduce the stand-by period amount that radio communication device 404 spends in the standby mode monitoring process for beep-page message.Optimize wake up can 1x layer 3 and 1x layer 1 in software change implement.
In addition, in low side chipset, the increase of park mode time may be highly profitable.For instance, optimize to wake up and can be used for that two SIM are two to be treated in (DSDS).Use the two radio communication devices 404 for the treatment of (DSDS) of two SIM to can be any radio communication device 404 that can use more than one radio access technologies (RAT) communication.For instance, optimize wake module 460 and can reduce CDMA and GSM conflicting between waking up.
For example two SIM are two treats that many SIM technology such as (DSDS) is popular feature in China, India, Southeast Asia, Latin America and other market.For have competitiveness in the two market for the treatment of (DSDS) of the two SIM of utilization, radio communication device 404 can have optimal power consumption and lower hardware cost.For instance, the radio communication device 404 that has higher power consumption and dual collector may not be treated to compete in (DSDS) market at two SIM pairs.Therefore, reduce two SIM pairs and treat that the hardware cost of (DSDS) radio communication device 404 and power consumption are desirable.
Fig. 5 shows according to the sequential chart of the optimization awakening mode of some embodiments of the present invention radio communication device 104.The time slot that sequential chart comprises the paging channel that is divided into four sub-slots 527a-d or frame.Sub-slots 527a-d can divide by sub-slots border 541 and boundary of time slot 529.For the sake of simplicity, only boundary of time slot 529 of mark and sub-slots border 541.In some configurations, the duration of sub-slots 527a-d can be 20 milliseconds (msec), and the one of cutting apart Paging Channel Slot to form two 80msec capable of being combined, defines as IS-2000 standard is lower.In addition, sub-slots 527a-d can be relevant to time slot cycle index (SCI).
In shown sequential chart, beep-page message receives sub-slots 476 can be set as sub-slots 3 (, the 3rd sub-slots 527c).In the time that beep-page message reception sub-slots 476 is set as sub-slots 3, radio communication device 104 until just just wake up before the 3rd sub-slots 527c (for example, in park mode 525a-b and do not enter standby mode) with paging receiving message and carry out page match.Therefore, radio communication device 104 can remain in park mode 525 during the first sub-slots 527a and the second sub-slots 527b.Before the 3rd sub-slots 527c, radio communication device 104 can wake in time to carry out preparation routine 533 up and obtain program 535 again.Obtaining program 535 can comprise with base station 102 and synchronize, aim at, determine with base station 102 which base station 102 is for best etc. again.
Radio communication device 104 can receive 531 beep-page messages during the 3rd sub-slots 527c.For this example, suppose that base station 102 just sends beep-page message during the 3rd sub-slots 527c.If base station 102 does not send beep-page message in the 3rd sub-slots 527c, radio communication device 104 can keep awake until receive 531 beep-page messages or complete the 8th sub-slots (not shown) so.If beep-page message is not included in any one of the 3rd sub-slots 527c sub-slots afterwards, radio communication device 104 can receive beep-page message sub-slots 476 and be reset to the first sub-slots 527a so, the sub-slots number 464 of storing waking up in record 462 is reset to the first sub-slots 527c, and is 0 by the count resets of waking up in record 462.In this way, wake record up 462 renewable.
If radio communication device 104 receives 531 beep-page messages in the 3rd sub-slots 527c, radio communication device 104 can increase progressively the counting 466 waking up in record 462 so.Radio communication device 104 can adopt decoding paging messages program 537.If beep-page message is empty general beep-page message (GPM) 488, so radio communication device 104 immediately (for example,, in the 4th sub-slots 527d) enter park mode 525d.If beep-page message is direct paging message 486, radio communication device 104 can be carried out joining procedure 539d so.
If radio communication device 104 is paging receiving message in the second sub-slots 527b subsequently, radio communication device 104 can reset and wake the counting 466 in record 462 up so.In addition, radio communication device 104 can produce stored sub-slots number 464 is designated as to the second sub-slots 527b but not the 3rd sub-slots 527c newly wake up record 462.This is in detail display more in Fig. 6 below.
The sequential chart that it should be noted that Fig. 5 illustrates the beep-page message receiving via paging channel but not the data that above receive at quick paging channel (QPCH) or the timing of position.Radio communication device 104 described herein monitors paging channel, but not QPCH.In other words, beep-page message does not receive via quick paging channel.
Embodiments of the invention described herein can be worked in the situation that existing or not having QPCH.The in the situation that of QPCH, QPCH can fail or miss the Paging Indicator position of indication beep-page message on the horizon.In the case, radio communication device 104 will wake up and monitor beep-page message based on optimizing wake module 460.
Fig. 6 shows according to another sequential chart of the optimization awakening mode of some embodiments of the present invention radio communication device 104; The sequential chart of Fig. 6 can comprise boundary of time slot 629, sub-slots border 641, sub-slots 627a-d, preparation routine 633, obtain program 635 and decoding paging messages program 637 again, and it is similar to the counter element 529,541, the 527a-d, 533,535 and 537 that describe in conjunction with Fig. 5 above.Sub-slots 627a-d can be relevant to time slot cycle index (SCI).
If radio communication device 104 is paging receiving message in the second sub-slots 527b subsequently, radio communication device 104 can reset and wake the counting 466 in record 462 up so.In addition, radio communication device 104 can produce stored sub-slots number 464 is designated as to the second sub-slots 527b but not the 3rd sub-slots 527c newly wake up record 462.
In shown sequential chart, in the time of paging receiving message in the second sub-slots 627b, beep-page message receives sub-slots 476 can be set as sub-slots 2 (, the second sub-slots 627b).If beep-page message receives sub-slots 476 and is set as sub-slots 627 but not the second sub-slots 627b, radio communication device 104 can receive beep-page message sub-slots 476 and change into the second sub-slots 627b so.
But in some instances, radio communication device 104 can be until have met or exceeded continuous sub-slots threshold value 474 just beep-page message is received to sub-slots 476 changes into the second sub-slots 627b.For instance, radio communication device 104 can receive four follow-up beep-page messages in the second sub-slots 627b, thereby makes to equal 4 for the counting 466 waking up in record 462 of described Record ID 472.Radio communication device 104 can then receive single beep-page message in the 4th sub-slots 627d.If sub-slots threshold value 474 is set as being more than or equal to 3 continuously, radio communication device 104 can not change beep-page message reception sub-slots 476 so.Then, if radio communication device 104 receives follow-up beep-page message again in the second sub-slots 627b, so the counting 466 of original record can increase progressively and beep-page message receive sub-slots 476 can keep the second sub-slots 627b.In this way, if base station 102 sends a limited number of beep-page message in different sub-slots 627a-d, when base station 102 sends to beep-page message when waking the relevant sub-slots 627a-d of the sub-slots number 464 stored of record in 462 up again, radio communication device 104 can still be carried out optimization wake up procedure so.In addition the periodic ranging message receiving at different sub-slots 627a-d place owing to error, reflection etc., will have minimum influence to optimizing wake up procedure.
Turn back to Fig. 6, in the time that beep-page message reception sub-slots 476 is set as the second sub-slots 627b, radio communication device 104 for example, until the second sub-slots 627b just wakes (, in park mode 625a) up with paging receiving message and execution page match.Therefore, radio communication device 104 can remain in park mode 625a during the first sub-slots 627a.Before the second sub-slots 627b, radio communication device 104 can wake in time to carry out preparation routine 633 up and obtain program 635 again.This optimizes wake up procedure and allows radio communication device 104 to remain on lasting cycle long period in park mode 625.
Radio communication device 104 can be during the second sub-slots 627b paging receiving message 631.For this example, suppose that base station 102 just sends beep-page message during the second sub-slots 627b.If radio communication device 104 receives beep-page message 631 in the second sub-slots 627b, radio communication device 104 can increase progressively the counting 466 waking up in record 462 so.Radio communication device 104 also can adopt decoding paging messages program 637.If beep-page message is empty general beep-page message (GPM) 488, so radio communication device 104 immediately (for example,, in the 3rd sub-slots 627c) enter park mode 625c and keep in park mode 625d in the 4th sub-slots 627d.
If beep-page message is direct paging message 486, radio communication device 104 can be carried out joining procedure 639c in the 3rd sub-slots 627c so, and carries out joining procedure 639d in the 4th sub-slots 627d.If radio communication device 104 has completed joining procedure 639c in the 3rd sub-slots 627c, radio communication device 104 can enter park mode 625d in the 4th sub-slots 627d so.Generally, as allowing radio communication device 104 to remain in standby mode, the optimization wake up procedure of describing in embodiments of the invention continues the less time.This causes power to be saved increases.
Fig. 7 show according to some embodiments of the present invention for optimizing the flow chart of the method 700 of waking up.Method 700 can be carried out by radio communication device 104.Radio communication device 104 can receive sub-slots 476 places at beep-page message and receive 702 beep-page messages.As discussed above, beep-page message receives sub-slots 476 and for example can be, corresponding to the one of sub-slots (, sub-slots 527a-d) of time slot cycle index (SCI) that is assigned to radio communication device 104.Radio communication device 104 can detect 704 empty general beep-page message (GPM) 488 and/or direct paging message 486 in sub-slots 527a-d.
Sub-slots 527a-d can be corresponding to sub-slots number.For instance, the second sub-slots 527b can be corresponding to sub-slots number 2.Radio communication device 104 can then determine described in 706, whether sub-slots number mates with the active sub-slots number 464 of storing waking up in record 462.
Be not stored sub-slots number 464 if wherein detect the sub-slots number of 704 beep-page messages, radio communication device 104 can receive beep-page message sub-slots 476 708 to first sub-slots (for example, the first sub-slots 527a) that reset so.Radio communication device 104 can 710 be also 0 by waking that record 462 counting 466 reset up.It is stored sub-slots number 464 that radio communication device 104 can set 712 by sub-slots number.Carry out the renewable record 462 that wakes up of step of 708 beep-page messages that reset, reset 710 countings 466 and/or setting 712 sub-slots numbers 464.
Radio communication device 104 can determine that 720 beep-page messages that receive are for empty general beep-page message (GPM) 488 or direct paging message 486.If the beep-page message receiving is empty general beep-page message (GPM) 488, radio communication device 104 can enter 722 park modes so.In the case, radio communication device 104 can enter park mode until beep-page message receives the next son time slot that sub-slots 476 defines.Radio communication device 104 can be followed again start method 700.
If the beep-page message receiving is direct paging message 486, radio communication device 104 can be carried out 724 access programs so.Once executed 724 access programs, radio communication device 104 just can enter 722 park modes.Radio communication device 104 can be followed again start method 700.
Are stored sub-slots numbers 464 if wherein detect the sub-slots number of 704 beep-page messages, radio communication device 104 can increase progressively 714 and wakes record 462 counting 466 up so.In this way, upgrade and wake record 462 up.Radio communication device 104 can then determine whether 716 countings 466 are more than or equal to continuous sub-slots threshold value 474.
If counting 466 is more than or equal to continuous sub-slots threshold value 474, radio communication device 104 can receive beep-page message sub-slots 476 and adjust 718 for stored sub-slots number 464 so, and this renewal wakes record 462 up.Based on determining 720, radio communication device 104 enters 722 park modes or carries out 724 joining procedures, as described above.Radio communication device 104 can be followed again start method 700.
If counting 466 is not greater than or equal to continuous sub-slots threshold value 474, radio communication device 104 can not made adjustment to beep-page message reception sub-slots 476 so.Radio communication device 104 can then determine that 720 beep-page messages that receive are for empty general beep-page message (GPM) 488 or direct paging message 486.Based on determining 720, radio communication device 104 enters 722 park modes or carries out 724 joining procedures, as described above.Radio communication device 104 can be followed again start method 700.
Fig. 8 shows according to some embodiments of the present invention for optimizing the flow chart of the method 800 of waking up between the transfer period at pseudo noise (PN) code 470.Method 800 can be carried out by radio communication device 104.Radio communication device 104 can have for a PN code set up wake up record 462.The two PN code of radio communication device 104 from a PN code moving 802 to main system.Radio communication device 104 can be stored waking up of 804 the one PN codes and record 462.For instance, the record 462 that wakes up of a PN code can be through storing 804 for using in the future.
Radio communication device 104 can determine whether 806 the 2nd PN codes have corresponding waking up and record 462.In other words, radio communication device 104 can determine whether to set up waking up of the 2nd PN code and record 462.Record 462 if set up waking up of the 2nd PN code, radio communication device 104 can use waking up of 816 the 2nd PN codes to record 462 so.In this way, radio communication device 104 can from a PN code wake up record 462 be switched to the 2nd PN code wake up record 462.
Record 462 if do not set up waking up of the 2nd PN code, radio communication device 104 can produce newly waking up of 808 the 2nd PN codes and record 462 so.It is the first sub-slots (for example, the first sub-slots 527a) that radio communication device 104 can be set the sub-slots number 464 of storing of the wake-up counters for the 2nd PN code 810.
It is the first sub-slots (for example, the first sub-slots 527a) that radio communication device 104 can receive beep-page message sub-slots 476 initialization 812.Radio communication device 104 can be 0 by counting 466 initialization 814 that wake record 462 up for the 2nd PN code.
